Exception Property (_EasyDAItemChangedEventArgs)

Gets the current exception. Contains null reference when no exception.

Syntax

Visual Basic
C#
C++/CLI

'Declaration
 
<CanBeNullAttribute()>
Property Exception As Exception

'Usage
 
Dim instance As _EasyDAItemChangedEventArgs
Dim value As Exception
 
instance.Exception = value
 
value = instance.Exception

[CanBeNull()]
Exception Exception {get; set;}

[CanBeNull()]
property Exception^ Exception {
   Exception^ get();
   void set (    Exception^ value);
}

Remarks

Your application code should check the Exception first, before accessing the operation data properties.

If you only need to test that the operation has succeeded, you can also use the OpcLabs.BaseLib.OperationModel.OperationEventArgs.Succeeded property.

This property is not serialized into XML. Instead, OpcLabs.BaseLib.OperationModel.OperationEventArgs.ErrorMessage is serialized. Deserializing from XML creates a base OpcLabs.BaseLib.OperationModel.OperationEventArgs.Exception object with just the message.

Requirements

Target Platforms: .NET Framework: Windows 10 (selected versions), Windows 11 (selected versions), Windows Server 2012, Windows Server 2016; .NET Core, .NET 5, .NET 6: Linux, macOS, Microsoft Windows
